WHY A SOIL GAS SURVEY? The best method to detect fuels and solvents in granular soil Value - the most testing for your dollar Non-disruptive to site activities Rapid test results for quick decisions THE EST SOIL GAS SURVEY Description of sampling methods Summary of sample concentration data Soil gas concentration contour maps Data evaluation Recommendations for further testing or remediation CHEMICALS DETECTED Halogenated hydrocarbons (e.g. common solvents and chlorofluorcarbons (CFCs) Aromatic hydrocarbons (e.g. common fuel components) Fuel additives (e.g. MTBE, TBA, TAME, etc.) Methane and other fixed gases Ketones (e.g. Acetone, Methy Ethy Ketone, etc.)

Mobile Laboratory

EST's ability to analyze soil gas samples on-site allows placement of subsequent test probes based on current field data, thus eliminating the wasted time and expense of unnecessary sampling and analysis.

EST's probe installation technique and on-site laboratory analyses have received the approval of numerous regulatory agencies including the California Regional Water Quality Control Board (CRWQCB), Los Angeles Region. EST operates from corporate offices in Irvine, California.

EST offers telephone consultations and will assist clients in evaluating the application of soil gas sampling and analysis to specific sites. EST also aids clients in preparing work plans and proposals suitable for submission to regulatory agencies. EST soil gas survey teams include experienced chemists, hydrogeologists and field technicians. Data compilation is computerized on-site for rapid turnaround of laboratory results. EST provides full soil gas survey reports, including tabulated concentration data, soil gas concentration contour maps, and data evaluation.

EST Soil Gas Sampling system EST's proprietary sampling system allows fast, accurate and cost-effective surveys. Our own patented design permits easy deployment of equipment and very accurate drilling. The EST HarpoonTm The EST HarpoonTm is used to sample soil gas during hollow-stem drilling. Using the Harpoon, soil may be collected in addition to soil gas using standard drive-sampler techniques.
